Timo Perthel put the home side in front with a smart side-footed finish but the Zebras were soon pegged back as Jan Fießer's header looped over Duisburg keeper Felix Wiedwald for the midfielder's third goal of the season. However, a foul by Daniel Ischdonat on Ranisav Jovanovic gave Branimir Bajic the chance to seal the win from the spot, and that he did to ensure Sandhausen missed the opportunity to move level on points with 16th-placed VfL Bochum 1848.
